Prepare for the winners of **IOCCC28**. > However these are not the 2024 droids you are looking for. :-) The HTML menu (both JavaScript and non-JavaScript) has been updated. The `Status -> Rules and guidelines' have been replaced with two separate menus `Status -> IOCCC rules` and `Status -> IOCCC guidelines`. Added a new top level `social.html` page: built from a new `social.md`. Sorted rules for building specific web pages in the top level `Makefile`. Added `make social` to make the `social.html` page from `social.md`. The `bin/gen-top-html.sh` now is able to process a argument of **social** to process the new top level `social.html` page. Changed `bin/gen-top-html.sh` VERSION from "2.0.0 2025-03-13" to "2.0.1 2025-07-25". Below `About -> Home page` a new `About -> IOCCC social media` menu item as added. Because the menu change touched every HTML file, we changed the general copyright date range for HTML files from "1984-2024" to "1984-2025" due to the extensive changes made for **IOCCC28**. Those markdown files that were modified in 2025 had their copyright date range also changed from "1984-2024" to "1984-2025". Rebuilt tarballs and sitemap due to the extensive HTML rebuilding. Ran `make update` to perform the above.

# Twenty First International Obfuscated C Code Contest
|
|
|
|
|
|
## Standard IOCCC stuff
|
|
|
|
View the `index.html` web page for the given winning entry for information on how
|
|
on how to compile it and how to run the winning program.
|
|
Look at the winning source and try to figure how it does what it does!
|
|
You may then wish to look at the Author's remarks for even more details.
|
|
|
|
Some ANSI C compilers are not quite as good as they should be. If
|
|
yours is lacking, you may need to compile using gcc instead of your
|
|
local compiler.
|
|
|
|
|
|
### Historical note:
|
|
|
|
The IOCCC has a website and now has a number of international mirrors.
|
|
The primary website can be found at [www.ioccc.org](https://www.ioccc.org).
|
|
|
|
|
|
### Historical update:
|
|
|
|
The IOCCC website once had a number of
|
|
[international mirrors](https://web.archive.org/web/20201030210517/https://www.ioccc.org/mirror.html).
|
|
As of 2020 Dec 29, [GitHub](https://www.github.com) serves as the distributed server farm for the
|
|
[IOCCC winner repo](https://github.com/ioccc-src/winner) that GitHub renders as
|
|
[Official IOCCC website - www.ioccc.org](https://www.ioccc.org).

## Remarks on some of the entries
|
|
|
|
We believe you will be impressed with this year's winning entries. We had
|
|
a very difficult time picking a single best from among the other entries
|
|
because the overall quality of the submissions were so high.
|
|
|
|
This year we selected the top 4 entries for particularly high honors:
|
|
|
|
* [Balanced use of obfuscation - Gold Award](zeitak/index.html)
|
|
|
|
A very extremely subtle and twisted piece of source code!
|
|
Even if you start with the zeitak.alt.c source,
|
|
you will still have a very challenging time to understand it!
|
|
|
|
* [Most elementary use of C - Silver Award](hamano/index.html)
|
|
|
|
A fun program that could also have won "Best abuse of
|
|
Ghostscript" because it managed to create some PDF files
|
|
that Ghostscript could not read.
|
|
|
|
* [Best use of cocoa - Bronze Award](vik/index.html)
|
|
|
|
A picture within a picture is worth more than a
|
|
thousand (4 byte) words. :-)
|
|
|
|
* [Most complex ASCII fluid - Honorable mention](endoh1/index.html)
|
|
|
|
When you see this program in action, you too will
|
|
very likely say
|
|
[wow](https://web.archive.org/web/20240626134108/https://twitter.com/ioccc/status/247140812683628545)
|
|
as we did!
|
|
|
|
But don't ignore the other winning entries! There are games, utilities,
|
|
eye candy, calculators and graphical tools to explore.
|
|
|
|
This year, [Yusuke Endoh](../authors.html#Yusuke_Endoh) won with two entries, one of which
|
|
([endoh1](endoh1/index.html)) won the special [Honorable
|
|
mention](endoh1/index.html) award. Eight of
|
|
the winning entries were from people who won in previous years.
|
|
|
|
This year we had a number of authors from Asia. We saw [our second
|
|
entry from China](hou/index.html) and [our first from Korea](kang/index.html). We are pleased to see
|
|
outstanding entries from areas of the world that have not been
|
|
active [in past contests](../years.html). Will we see an upswing of entries
|
|
from [South America](https://en.wikipedia.org/wiki/South_America),
|
|
[Africa](https://en.wikipedia.org/wiki/Africa) and
|
|
[Antarctica](https://en.wikipedia.org/wiki/Antarctica) next year? :-)
|
|
|
|
Please note that judging is done completely anonymously. Please
|
|
do NOT reveal your identity in your source code. In the future we
|
|
may disqualify entries that reveal the identity of the submitter!
|
|
|
|
There were some outstanding entries that did not win. Unfortunately
|
|
some very good entries lost because they:
|
|
|
|
+ would take years to execute
|
|
|
|
+ were way way oversize and didn't even attempt to justify their
|
|
excess by a clever abuse of the rules
|
|
|
|
+ obfuscate themselves by simply invoking a complex
|
|
state machine
|
|
|
|
+ depend on a single obfuscation trick
|
|
|
|
+ could only be run on a particular vendor's platform
|
|
|
|
+ were very similar to previous winning entries
|
|
|
|
+ were based on an overused theme such as yet another
|
|
fractal display program
|
|
|
|
+ didn't work as documented
|
|
|
|
We hope the authors of some of those entries will fix and re-submit
|
|
them for the next IOCCC.
|
|
|
|
There is a risk in submitting an entry that is similar to a well
|
|
used theme by previous winning entries. Previous entries set a very high
|
|
bar. A new winning entry must not only compete against other submissions
|
|
form the current year, they must also excel over similar winning entry
|
|
in some particularly impressive way.
